Sig Sauer P365-FUSE & TLR-7 Sub IWB Holster

Sig Sauer P365-FUSE IWB Kydex Holster for Streamlight TLR-7 Sub 1913

This Inside Waistband (IWB) light-bearing Kydex holster is precision molded for the Sig Sauer P365-FUSE equipped with a compatible Streamlight TLR-7 Sub 1913-series weapon light. Designed for concealed carry, it provides adjustable retention, an optics-ready profile, and smooth, rounded edges for comfortable all-day wear.

The holster is also confirmed to fit a P365-FUSE slide installed on a Mischief Machine Alpha Gen 3 grip module when equipped with a compatible Streamlight 1913 weapon light.

Required Streamlight Weapon Light

This holster is designed for the following weapon-mounted lights:

• Streamlight TLR-7 Sub or TLR-7 X Sub 1913, Part #69402, using the #1 key
• Streamlight TLR-7 X Sub USB, Part #69407
• Streamlight TLR-7 HL-X Sub, Part #69505

Important: Holster retention is created around the mounted weapon light rather than the pistol itself. The firearm will not retain properly unless a compatible light is correctly installed.

This holster is not compatible with the Streamlight TLR-7 Sub SIG version.

Precision-Molded for Concealed Carry

Each holster is vacuum formed over a precision-machined mold developed from a CAD model of the actual firearm and weapon light combination. Every holster is formed, trimmed, folded, and finished in-house before being tested with the actual pistol and light to verify proper fit, function, and retention.

User-adjustable retention allows the draw resistance to be fine-tuned for individual preference.
